Fifa'. 2 is a partial l'ront elevation ot.' the suspension ineehanismshowing the traek rail in ('l'oss settion.

Figs. Il and -l are News' eorrespondingI t0 Fig. 2. showing modifiedhangers wint-hills() einliod)7 in)r invention.

Vig'. 5 eorresponds to Fig. it' shows a pair of rails and hers e|nplo\'ed with a single Still another inodilieation is, shown in Fig. (lwhieh corresponds to Figs. 2. il and l. Init comprises a fixed rail orrails trom whieh the door is suspended.

Fig'. 7 is a moditeation of the arrange,- nient o'll Fig'. t3 in which npair of lz'lils are employed. spared apart hy a distance substanfiall)lequal to the width ot' the. door.

Figs, S and 9 show still further modifications ot' my invention andeorrefspond to a portion ot' Fig. l.

Details of the suspension strueture of Fig. l. are shown in Figs. v10and 11, and the pivotal mountiim` ot' the rail is Shown in plan in Fig.l2.

In Figs. 1 and i2, 15 designates one of the door poste. 16 the linteland 17 a ceiling l'ieam extending inwardly away from the plane ot' thedoor opening,

Suspended from the ceiling beam'l? by 'a pair ot' adjustable links 18 isa relatively stationary track lail 19. .As shown in Fig. 2, thisl railma)Y eomprise an I-beam of well known form with whieh a pair 0ffrustloeonieal rollersl 20 are adapted to eoperate. lt is furthermorepreferablyjoined to the lintel at its inner end by means of aslidablepivot lil" to permit freedom of movement as t'ar ils-.allowed l thesuspension links. (Seel"ig "s. and 12.) The rollers are mounted on aYoke or elers 21 so that they are on opposite sides; of they trat-k.

The door, which maw7 haa'e one or more seetions. eomprises. in the.arrangement shown. an upper door section 92 having `uidewaw's 24. and alower door section 25, haring guide rollern 2G near it# lower COI-exeept that suspension memdoor.

of my invention i in any suitable manner; for example, they other handbe supported in fixed may comprise a pair of bolts 29 and 30, joined bya turn-buckle 3,1.

The link 28 ma be similarly constructed, or, as shown in tlie drawings,it may comprise a pair of nuts .or sockets 32-33 joined by a stud 34having oppositely extending left and right hand threaded projections 35.

At the inner end of the rail 19 I prefer to utilize wedge-shaped blocks36, one of which is shown, for the purpose of starting the rollers 20away from the plane of the door opening when the up er door section isfirst forced upwardly by t e hoisting mechanism.

Instead of links 18 and 28 of Fig. 2, chains 38 and 39 may besubstituted as shown in Fig.` 3, or the adjustment of the length of thelink may be obtained by vother means, as, for example, that shown 'inFigs. 4, 10 and 11. V

As yhere shown, a link 40 replaces the link 28 of Fig.4 2, and for thelinksl 18 is substituted an adjustable link 41, composed of a member'42having a plurality of holes 43 and a`member 44 havin a slot 45. The

` members are attached by olts 46 which extend throu h one or more ofthe holes 43 and tliroug the slot 45.

Instead of'utilizing a single tra-ck 19 and a single hanger as in thearrangement of Figs. 1 to 4 inclusive, two or more rails or han ers maybe employed as shown in Fig. 45. ach of these hangers corresponds tothat of Fig. 3 in the arrangement illustrated, but of course anysuitable arrangementmay be utilized.

In the modification of Fig. 6, a pair of channel shaped suspension rails48 and 49 are employed. `These rails may be close together as in ig. 6,or spaced at considerable distance 'apart as in Fig. 7. They may besuspended as in the previous figure-s, `but this is not. essential andthey may on the position by: any suitable means.

A pair of rollersl 50 and 5l cooperate with the respective rails und aremounted near the. respective ends of u shaftl In the arrangement of Fig.6 a sleeve. 53 spaces the rollers apart and is coniufcted to the. doorbracket 27 by hinge block 8T and link 40 as in the arrangement of Fig.4.

In the structure of Fig. 7, the shaft 52 'turc itself.

is of considerable length and a hunger 54 is pivotally mounted upon itnear its middle ioint. beinglicld in position by collars 55. 1` hehanger is pivotally connected to the hinge block 87, the arrangement ofparts being such that the hanger 54 permits the door to swing in oneplane and the pivotal connection between the hanger andthe hinge blockpermit the door to swing in another plane.

If the rail 19 is sus ended by links 18 as is Figs. '1 and 8, the coormay have rollers such as rollers 56 mounted on door brackets 57, thebrackets being rigidly attached to the top of the door as shown in Fig.'8.

Another modification in which a stationary rail 58 is provided is shownin IFig. 9; The rollers 20 of the yoke 21 'are connected to the door bya chain 39 as in Fig. 3.

Any suitable hoisting mechanism may be employed such as that shown inFig. 1, for example, and designated 61. This mechanism comprisescounter-weights 62 suspended byl chains 63 which extend overpocketsheaves 64 and are connected to the lower door section 25 bycorner brackets 65. It further comprises a hand chain 66 which may' beactuated in the usual manner.

section, this section is first.-raised and voverlaps the upper section22; upward pressure is then applied to both sections together andtemporarily a force is exerted through the link 28 which tends to pushthe roller 20 into engagement with the inclined cam surface. of thebracket 36. This action assists in breaking in" the door at the top andas the hoisting is continued, the upper end of the. door swingsinwardly, the rollers 2() riding on the rail 19 until the dooroccupies'the 110 position shown in broken lines in Fig. 1.

0f `course-'the bracket 36 may be omitted and will be of. no vu lue.when chains or flexivble Suspenders such as the chains 39 are employed.

Attention is particularly directed 'to the fact that the guidt` andsupporting rail itself or the connection `between the rail and the door,or both. are yielding structures, or, in other words, they permit amaterial freedom of movement and thus not only relieve the door fromstresses and stra-ins which tend to warp and twist il. but also largelyeliminate strains upon the. supporting struch Thisl yielding ot thesupporting rail is also facilitated b v the pivotal or hinge connectionwhich is establishedbetween the rail and its end support: for example,the arrangement clearly shown in Fig. 8 permits the rail l!) to risesomewhat 130 when the dooris first hoisted as well as to swing about thepivot as 'an axis to follow 'tending to interfere with its operation.

Further modlfications. will suggest themselves to those skilled vinthisl art, .and I intend that no limitations be imposed-jo'ther-A thanthose indicated in ap-pencledelaims.

What 'I claim is:

1. The combination with a door frame and a rail extending inwardly abovethe, door opening, of a door, hoisting means therefor actingsubstantially in the plane of the door opening, and means movable inrelation to the rail for suspending the door from the rail, saidsuspending means comprising a non-rigid connection.
